Astrophotographer captures spectacular photo of Antennae Galaxies dueling in deep space

Astrophotographer Greg Meyer took aim at the constellation Corvus to capture a majestic view of the Antennae Galaxies, whose once spiral forms have been rendered chaotic as they merge into a single elliptical monster of a galaxy.

The deep space image captures a fleeting moment in a titanic struggle that has lasted hundreds of millions of years, as the gravitational influence of the galaxies NGC 4038 and NGC 4039 pulls at one another to create chaos on a truly cosmic scale.

“I have a Sky-Watcher Esprit 120 [telescope] with a focal length of 840mm, which is a little short for most galaxies, this being galaxy season now,” Meyer told Space.com in an email. “So whenever I see a picture of a galaxy, I see if it is within reach for me by checking Astrobin for photos taken with the same scope. And since this is such a cool image of 2 galaxies, with an amazing backstory, I had to go for it.”

Meyer’s shot reveals the orange-yellow cores of the dueling galaxies glowing in a maelstrom of interstellar dust, gas and stars, from which a pair of sweeping “tidal tails” made from elongated spiral arms reach out for light-years on either side. The sweeping structures bear a striking resemblance to the sensory organs sported by members of the insect world, which eventually granted them the nickname of the Antennae Galaxies.

The cosmic tug of war has triggered an outburst of star formation, which has led to the creation of “super star clusters” in the vast antenna-like arms, according to NASA. 90% of these goliath clusters are likely to disperse as the galaxies merge and settle, while others will persevere as globular clusters.

Meyer dedicated just under 21 hours of observation time collecting light from the distant galaxies using a series of astronomy filters as they glowed in the skies over the Starfront Observatory in Rockwood, Texas. The light data was then compiled and edited using Adobe Photoshop and Lightroom in concert with the astrophotography software PixInsight.
